Los sistemas de HVDC para la transmisión de grandes bloques de potencia se han incrementado gracias al desarrollo de la electrónica de potencia para aplicaciones de alta tensión. Se considera esta tecnología como una alternativa clara para la necesaria actualización de los sistemas de transmisión...
HVDC systems for bulk power transmission have been increased due to the development of power electronics for high voltage applications. This technology is considered as a prominent alternative for the upgrade of HVDC transmission systems. This entails operations and functional improvements in the...
Históricamente, la zona norte de Chile se ha caracterizado
por experimentar una serie de desastres naturales que han tomado la
vida de numerosas personas y causado innumerables daños
materiales. Una de las localidades más afectadas por estos eventos ha
sido la ciudad de Chañaral, localizada en la...
Resumen: Terremotos históricos y recientes (p. ej. los de 1906, 1985 y 2010) indican la repetición de un patrón espacial de la distribución de los daños sísmicos en Viña del Mar (Chile) que afectan sobre todo a la zona llana de la ciudad.
La ciudad de Viña del Mar, situada en el borde norte de la...
Summary:
Historical and recent earthquakes (eg those of 1906, 1985 and 2010) indicate the repetition of a spatial pattern of the distribution of seismic damage in Viña del Mar (Chile) that mainly affects the flat area of the city . The city of Viña del Mar, located on the northern edge of the g...
This thesis addresses the observer design problem, for a class of linear one-dimensional parabolic Partial Differential Equations, considering the simultaneous estimation of states and parameters from boundary measurements. The design is based on the Backstepping methodology for Partial Different...
In this thesis we present algorithmic and modeling contributions for Stackelberg games that help address challenges due to problem size. Stackelberg games consider that one player, called leader, commits a strategy first and the other player, named follower, observes this strategy and plays a bes...
In packet-based wireless communications, the first task of a receiver is to detect the
presence of a signal in the air and to determine a timing reference about it. This task is often
assisted by transmitting a known preamble sequence. The task has to be performed under
several impairments such a...
The general objective of this thesis is to address the problem of forest fires from a pre- ventive perspective, mainly motivated by the increase of this phenomenon worldwide and exacerbated by climate change. The current incidents indicate that preventive policy mea- sures must be taken to reduce...
Seawater (SW) in mining is used in a desalinated or non-desalinated mode and it is presented as a favorable alternative to supply the lack of water in this industry. The first option means high investment costs and energy consumption translated into greater pollution, either by the emission of gr...
